7-Mode ONTAP 8.1.2P4 as a secondary system and OSSV on Windows as a primary. I have a relationship established and have been doing manual, periodic "snapvault update"s to bring across changes.
I want to schedule this, but I'm not sure that snapvault snap sched is what I'm after or not. It seems to be about retaining snapshots of data and really I just want to keep one copy -- as up to date as possible (once an hour or so). We're preparing for a migration.
Maybe I do something like:
snapvault snap sched -x hourly 1@mon-fri@0-23

you are right, if you keep just one Snapshot you can set this with your mentioned scheduler.
With your settings, every hour will be made a snap and the previous snap will be deleted automaticly.
Notice: often the connection between the Filer and the OSSV Clients/Hosts are not optimal (bandwith?)
and in that case, there is a bigger change rate, 1 hour could be pretty narrow for transferring new data to the destination.

Thanks, Lutz. I'll give this a try. Our change rate has (so far) been as such that I can do an update within one and a half hours even after 7-8 hours of lag. But your point is well taken. I'll probably start with a wider window to be safe.
